To measure
the angle using Kinemage, go to the Other pulldown, click on Measure.
Now click point A, then point B and last point C. The lower right
will give the angle.
**What is the measure of <ABC using Kinemage?
______.
Is the value in close agreement with your approximation?_______.
The distance shown at the lower right will be
the distance between the last two points clicked. Do not be concerned
about the
"dhr" value, we will demonstrate this in Tutorial III.
To turn off the measure option, go back to the Other pulldown
and simply click off Measure the white lines that were traced
over the angle will
be removed.
Remove the green angle from the screen by clicking
off the X from the box named angle, at the right side of the screen.
Click on
rectangle.
**Estimate the perimeter of the rectangle by counting
squares.
What is your estimate of the rectangle? ______
**Measure the perimeter by measuring the distance
of each of the line segments in the rectangle using Kinemage.
What is your answer?________
**From your knowledge of rectangles, what should
each of the angles of a rectangle be equal to?________
**Using Kinemage what values do you get for each
angle?____. The
sum of the angles of a rectangle is ________.
Clear the screen of the rectangle. Call up the
triangle.
**What is your estimates for: <A=______ <B=_______
<C=________
**What is your estimate for the perimeter of triangle
ABC?______
**Using Kinemage find <A=______ <B=________ <C=_______
**The perimeter of triangle ABC using Kinemage is: ___________
Some computers have built in calculators which
may help when doing computations with decimals. Ask your teacher
if your
computer has a built in calculator.
It is possible with Kinemage to draw your own
images. First clear the screen of all images, leaving only the
points on the screen. Go to the Other pulldown and click on drawline.
When the drawline box appears click "ON". NOTE: Make
sure the measure command is clicked off or measure lines will
also appear. Click two consecutive points and a line will appear.
You can continue to draw line segments between any two points.
If you wish to erase the last line you drew, simply click eraseline
at the right side of the screen. If you have drawn several lines,
clicking eraseline will keep erasing lines in order from the last
one drawn. If you wish to erase all lines quickly, return to the
drawbox command under the Other pulldown menu and click off. This
will remove all lines you have drawn.
Activities for Students:
1) Draw your initials using line segments. Measure
the distances and angles used to form the letters.
2) Try finding the interior angles of each of
the polygons shown. What is the sum of the interior angles of
each of the polygons shown?
3)If you are familiar with the Pythagorean theorem
a^2+b^2=c^2 find the diagonal of the square and rectangle. Check
your answer by measuring the diagonal using Kinemage.
3) Try drawing several angles and polygons and
measure their sides and angles.
